JACOB G. GBOIBLE, OF ANDEBSON, INDIANA.

GAS-PRESB URE REGULATOR.

Specification of Letters Patent.

Patented Nov. 5, 1918.

Application filed July 10, 1918. Serial No. 245,187.

To all whom it may concern:

Be it known that I, JACOB C. Gnoenn, a citizen of the United States and a resident of Anderson; county of Madison, and State of Indiana, have invented a certam new and useful Gas-Pressure Regulator; and I do hereby declare that the following is a full, clear and exact description thereof, reference being had to the accompanying drawings, in which like figures refer to like P ItS.

Thisinvention relates to gas pressure regulators particularly of the automatic type, and is an improvement over my former ap plication, Serial No. 219,209, filed February 26 1918.

The prime jeature of the invention 18 the provision of means for quickly attach ng or removing the valve from its support ng means. A further feature of the invention is the provision of means u on the valve for frictional engagement wit the valve supporting lever for holding the valve 111 engagement with its support, and at the same time ermit vertical adjustment of the valve.

A further feature of the invention is in so A constructing the valve attaching means that the valvewill be held against undue lateral swinging or rotating movement.

In the accompanying drawings which are made a art of this application, Figure 1 is a side e evation, part y in section, of a gas regulator showing the manner of attach1ng the valve with the valve supporting lever. Fig. 2 is a sectional view as seen on line 2-2, Fig. .1. Fig. 3 is an enlarged detail sectional view as seen on line 3- -3, Fig. 1. Fig. 4 is an enlarged central sectional view of a valve showing a modified means for attaching the valve to its hanger.

Referring to the drawings, 1 indicates a trap frame of a gas pressure re lator which is of the usual form, and pre erably formed of two sections, the lower sectlon havin a depression 2 therein which forms a latera ly extending channel 3, one end of which terminates in a sleeve 4, the ends of the sleeve being internalliv threaded for engement with a,,pipe ine (not shown). fi nmediately above the lower threaded ortion of the sleeve which is threaded a thimble 6, the upper end of which terminates in aseat 7 for the reception of a valve 8. The valve is emis formed a bridge 5 into ployed for regulating or stopping the flow of as through the thimble.

he valve 8 is suspended from one end 9 of a. lever 10, said lever bein pivoted in the channel 3, the pivoting point 11 -,being in close proximity to the end 9 of the lever. The inner end of the lever 10 is pivotally attached to'the well known form of diaphragm 12, through the medium of which the lever 10 is rocked on its pivot to raise or lower the valve 8 attached thereto.

The end 9 is of considerable less depth than the remainder of the lever 10 so as to form a vertical rib 14, in the opposite faces of which are formed vertical grooves 15. Extending through the flattened end 9 is an adjustable support 16, that portion of the support extending below the end 9, having a peripheral channel 17 therein for engagement with a hanger 18 of the valve 8 so as to suspend the valve from the support. The hanger 18 comprises a body portion 19 which is shown in the various figures as resting upon the top of the valve 8, and said body portion may be brazed, spotwelded or otherwise secured to the top of the valve, or as shown in Fig -1, a stud 20 may be formed at the axial center of the valve 8, which stud projects through an opening 21 in the body portion 19 and the upper end of the stud then upsetor riveted. When this form of means is employed for attaching the valve to the hanger, the stud will serve as a centering point for the hanger.

One end of the body'portion 19 is extended beyond the peripheral edge of the valve 8 and bifurcated to form spring fingers 22, which fingers are given a half turn so as to present the flat faces. thereof at right angles to the flat face of the body portion carrying the fingers. The spring fingers 22 are each provided with aninwardly bowed portion 23 adjacent to the free end of the finger, which bowed portions are adapted to sun into the grooves 15 of the rib l-l, when t e valve is properly positioned over the seat, the free ends of the spring fingers being flared outwardly so that they will readily ride over the ed es of the rib 14. The 0 posite end of the ody portion 19 is curve upwardly and the free end 24 thereof dis used over the body portion 19, said free en 24 having a longitudinally extending slot 25 therein for engagement with th channel 17 of the su port 16, the slot 25 being of suflicient wi th to snugly receive the reduced rtion of the support. Instead of forming t e hanger construction separate from the valve structure and then attaching the same thereto, the hanger and valve may be formed integral as may be found expedient.

One wall of the sleeve 4 is provided with a removable plate 26 whereby a ready access may be had to the interior of the sleeve and through the medium of which the valve 8 ma be removed from or engaged with the en of the lever 10. In introducing the valve into osition, the support 16 having previously een properly adjusted in the end of the lever 10, thervalve is moved inwardly in a straight line through the opening in the side of the sleeve 4, and the groove portion of the sup ort engaged with the slot in the end 24 o the hanger, and simultaneously with this operation, in view of the fact that the fin ers 22 are extending forwardly of the va ve, the flared ends of the fingers will contact with the rib 14 and ride over-the opposite faces thereof, and when the support has reached the inner end of the slot 25, the bowed portions 23 of the fingers will sna into the grooves 15 of the rib, thereby frictionally holdin the valve in supported position. When t e valve is to be removed, a strai ht outward pull is given to the valve, w ich will overcome the spring tension of the fingers 22 and permit the end 24 of the ban er to release from its support, the action o disengaging and replacing the valve being very easily and quickly accom lished. Furthermore, 1t Wlll be seen that y disposin the grooves 15 vertically, the valve can e adjusted vertically with respect to its seat, as occasion may require, without affecting the gripping action of the fingers, upon the rib. t wil likewise be seen that 1n view of the fact that a finger passes on each side of the rib 14, and the said rib'is stationary, the

fingers will serve to hold the valve against rotating or undue laterally swmgmg movement.

By attaching the valve to the lever 1n the manner herein shown, a defective valve can.

be readily removed and repaired or a new one inserted in its place without necessitating the cutting oil of the supply of gas an unreasonable length of time, which is necessary in repairing valves which are permanently secured to the operating lever, as 1t is necessary to remove parts of the regulator in that instance and return the sameto the factory in order to repair the same, while with applicants device, but a very few minutes are required to renew the valve and in fact the gas is only cut off the length of time that it takes to remove the plate 26 and return the same to position.

The invention claimed is:

1. In a gas pressure re lator, the combination with a lever, o a valve, means to support the valve from the lever and means carried by the valve for frictional engagement with parts of the lever to hold the valve on its support.

2. In a as pressure regulator, thecombination with a lever havln a rib thereon and a valve support carried by the lever, of a valve means to removably attach the valve to its support, and means on the valve adapted to frictionally engage said rib to hold the valve in position on its support.

3. In a as pressure regulator, the combination with a lever, and a valve support carried thereby, of a valve, a hanger on the valve adapted to engage said support and suspend the valve therefrom, and means carried by the valve for frictionally engaging parts of the lever for holding the valve in position.

4. In a gas pressure re ulator, the combination with a lever, an a valve support adjustably attached thereto, of a valve, means on the valve for engagement with said support, and spring fingers carried by the valve adapted to engage parts of the lever and hold the valve in position on its support and against rotation.

5. In a gas pressure regulator, the conibination with a lever, and an adjustable valve support carried thereby, said support hayin a channel, of a valve, a hanger attache to the valve and having a-slot for engagement with the channel of the support, and means for frictionally on aging the valve with arts of the lever, w ereby said valve may he quickly engaged with or disen aged from the lever.

6. n a gas pressure regulator, the combination with a lever, an adjustable support carried thereby, and a rib on the lever aving vertical grooves, of a valve, a pair of spring fingers carried b the valve ada ted to be engaged with t e grooves of sai rib to hold the valve against rotation, and means on the valve adapted to engage said support and sus end the valve.

In witness whereo I have hereunto affixed my signature.
